# Exercise 1
Write several chords containing all 12 notes spread out over at least three octaves. Like Obouhow, try to avoid repeating the same note in 
the same octave.

Write a function that helps to avoid repeating the same note in the same octave.

# Exercise 2
Write an additional chord where two or three notes remain in the same octave from chord to chord and list to the difference.

# Exercise 3
Alter one of these chords so that it contains two A flats and no G and try to hear the "error."

# Exercise 4
Construct a chord where a major triad will be prominent and the other nine notes will be secondary.

# Exercise 5
Form an Obouhow 12-note chord in three octaves, with four notes in each octave, where the notes of each octave are the same four-note Forte set.

# Exercise 6
Unlike Euler, Obouhow normally distributed the 12 notes rather equally over a wide range. Consider how he might have put more notes in the higher octave and less in the lower octaves.

# Exercise 7
Write a series of 12-note chords in such a way the the chords seem to be changing. Write another series in such a way that one realizes one is 
hearing a single 12-note chord repeated.
